Taking the drone abroad

Hi guys, I've recently purchased a new psa which arrives tomorrow
I will being going on holiday soon and want to take it with me.
What is the policy for taking these on the plane:
•can they be taken as hand luggage?
•do they have to be checked in as normal luggage in the hold?
• is there issues with transporting the lipo batteries on the planes?

I recently brought my p3p and two batteries from Norway to the US and back. I took it as hand luggage, and at the airport in Oslo I took out the batteries and sent them separately trough security. They told me it was not necessary to do that. But they swabbed the bird though There is a limit on how much lithium a battery can contain, but these batteries are far below that
